东海西北部无机颗粒物分布异常与水系及沉积物之间的关系分析

摘要:
本文研究了东海海水中无机颗粒物Fe,Al和Co的分布特征与水系及沉积物分布的关系。指出,上述元素在东海西北部含量最高,分布异常的主要原因是由于黄海沿岸流携带着大量悬浮物质引起的。又指出,在 32°N,125°E附近,由于受几股流系的阻挡,流速减慢,较多的悬浮体被聚集在这里。据推测,无机颗粒物Fe,Al和Co的分布异常区的逐年平均中心位置和范围,可能也是海底软泥分布的中心位置和范围。

AN ANALYSIS OF RELATIONSHIP AMONGTHE ANOMALY DISTRIBUTION OF INORGANIC PARTICULATE, THE CURRENT SYSTEMS, AND THE SEDIMENTSIN THE NORTHWESTERN PART OFTHE EAST CHINA SEA
Abstract:
The data of inorganic particulate of sea water in East China Sea was collected in June 1984. Horizontal distribution of a number of inorganic particulate, such as Fe, Al and Co, revealed that a high content appeared on every water layer in the northwestern part of the East China Sea. The authors pointed out these inorganic particulate elements distribution patterns has close relation with the current systems, and it has close relation with surface isolate mud distribution in the northwestern part of the East China Sea.
